ALPHA is a high-efficiency circulator fitted with an electronically commutated motor and designed for circulating liquids in heating systems. The pump features the highest energy rating on the market. ALPHA is designed with intelligent controls featuring a constant-pressure, proportional-pressure and constant-speed curve, each with three speed settings as well as an AUTOADAPT setting, removing the need to manually select the pump setpoint. The new toolless, removeable power connector results in fast and easy installation. Fewer callbacks can be expected due to its robust startup, self-venting ability and dry-running protection.
